Environmental medicine focuses on acute and chronic effects of chemical and physical environmental influences on health as measured objectively and perceived subjectively. Since these influences are very complex, continuously changing and only partially accessible in scientific experiments, subjective causal attributions can be difficult to prove or disprove. Patients with symptoms attributed to environmental triggers perceive health threats from commonly used chemical agents or electromagnetic radiation, frequently without objective findings. Typical examples are "multiple chemical sensitivity (MCS)", a generalized self-reported hypersensitivity towards ubiquitous chemicals, or "amalgam sensitivity", where symptoms are attributed to amalgam from dental fillings. Here, the reported symptoms are almost invariably unspecific and show a high overlap with other medically unexplained syndromes. Based on modern psychosomatic conceptualizations, many environment associated illnesses can be regarded as somatoform disorders and treated as such. Apart from a high psychiatric comorbidity, special attention should be paid to dysfunctional cognitions, emotions and behaviour, and the patient's often limited quality of life.     «
